STACKER.

To all whom it may concer/z:

Bo it known that we, TILLIAM T. hlt/CALL and DAVID Linvnnxen OmcNDonrr, citizens of the United. States, and residents ol Man- 1 hattan, in the county ol" ltiley and State ol' vating and piling up hay or grain into stacks. l It is intended primarily for the purpose ol` stacking grain which has been cut by a header, in which the heads ol' grain with a small proportion ol the straw are received into a box-like receptacle and 'is elevated to pilel the same in suitable stacks.

The invention is also applicable lor use :is a hay stacker by simply substituting lor the box-like receptacle a lork adapted to cooperate with the longer hay.

It is an improvement upon that general lorm ol stacker in which a triangular traine mounted upon wheels is provided with an elevated `framework carrying a trussed triangular' forli trame whose outer end is provided with a lifting lork and whose opposite end is connected by means ol" a rope with a winding drum for elevating the hay or grain.

Our invention consists in the novel con.- struction and arrangement ol the parts and combinations oli' parts forming an improved stacking device oli' the kind described as hereinafter more fully set forth.

Vln the drawing-Figure l represents a plan view. Fig. 2 a side elevation. Fig. 2 a detail view showing a different position of the end olt the grain receptacle. Fig. 3 is a liront elevation otthe entire machine. Fig. l is a plan view of the winding drum and its accessories. Fig. Lla is a section on line 4&- 4 ol Fig el, and Fig. 1lb is a section on line lhs-4l ot Fig. Ll. Fig. 5 is a plan view on larger' scale ol the steering device, and Fig. 6 represents an end view and a plan view ol' a .term ot fork traine to be used in the place ol the grain box when our invention is applied to stacking hay instead ol headed grain.

Relerring to Figs. l, 2, S, the l'raine ol the machi e is seen mounted upon l'our wheels, the two large wheels l, l in front, which are connected to the axle A by the usual ratchet and pawl connections employed in mowers so as to tnrn the axle when ther wheels are moving l'orward and thus supply power l'or the operation ol the winding drum herein- Specification of Letters Patent.

alter described. The other two wheels of the l'rame are arranged in the rear and are shown at J, J', and are constructed as caster wheels and (',operate with the steering devices as hereinafter described. The main frame oll the stacker is mounted upon sills consisting olI two side pieces G and G arranged in triangular relation to each other, resting at the l'ront ends upon the axle and connecied at their rear ends to the cross bar G", resting above the caster wheels, as seen in Fig. 5. ll is a central longitudinal supporting har connected at. its forward end by means oll a l'orh 'lli' to the axle A, as seen in Fig. il and connected :it itsl rear end to the cross bar G2.

Referring to Figs. l, 2, and 3, the stationary portion olI the framework consists olt two convergently arranged derrick bars L and lf on one side and L and L on the other, all ol'v which are mounted upon the sills olf the main trame and the apices of which convergent side bars on one side are connected to those on the other side by means ol a cross liar M, which l'orms the lulcrum upon which the hoisting and tilting trame turns which carries the load. This hoisting and tilting lranie is composed oil the bars F, O, Vil, arranged in triangular relation, which at the upper end are hung upon the cross bar Ivi, which carry at their outer ends the grain box U and at their rear ends are connected by a rope l to the winding drum, by the winding up ot which rope upon the drum the l'raine l), R, is tilted and the grain box U raised or lowered, The upper part olE the grain box is connected by bars Z, Z, to the top et' a traine S, S, lil which latter is lulcrumed upon the cross bar M and has rearwardly extending and rigidly attached inembers 8, S, and l0, l() arranged to cooperate with dumping devices as hereafter descrihed.

Rel'erring now to Figs. il, #lit and 4', the winding device consists ol the drum B, to which is rigidly Vlixed the bevel gear E meshing with a bevel gear F arranged in a plane at right angles and which latter bevel F also meshes with another bevel gear l) arranged upon the main axle A. Both the drinn B with its gear E and the gear l) are loose upon the axle A which extends entirely through the saine l'roni one running wheel l on one side of the machine to the other one l1 on the other side. C a sliding clutch arranged upon the axle A between the gear wheels E and D and connected to said axle hy ineans of a feather and groove a, so that said clutch C is free to inove longitudinally on the axle hut is compelled to rotate rigidly -with it. This clutch C is provided With engaging teeth on otli its sides, one olI vfl'iich sets of teeth is arranged to ensiinilar teeth on the gear E andthe other of which sets oiE teeth is arranged to the teeth on D, the engagement of said clutches heine` alternate according to the direction of the adjustment oi the clutch C. A Winding rope 1, see Fig. 2, is connected to the rear end oi the hoisting 4traine l), 0, and extends thence to the Winding drum B, seen in Fig. Il, around which it is adapted to he Wound to turn the hoisting traine P, O, R, upon its fulcruin liar in', in raising lowering the grain 7nox il (En one end of the drum n is arranged a ci ratchet teeth i" adapted to he engaged and locked hu ineans of a spring seated detent 2, operated hy a pull vrire t. The clutch C is ernhraced hy a forli on the end of an elhoiv lever 3, which is inlcrnined to the yolrc-shaned piece H2, and which elhow lever is operated cy a pull Wire il? /vhen it is desired to li chine is started i'oi 1rd l1 a load the inaand the clutch which slides on the axle il is thrown into engagement i h the gear E hy means oi" the lever 3 and pull Wire 1V, 'which latter passes hack to the operator-s position, Which upon a platlorin at the rear end ol' the inachine adjoining the dral't appliance i. This causes the druni to vrind loraard and pulls the rear end olthe hoisting irarne toivard the drnn and raises the l'ront end oll the hoisting lraine and consequently the load contained Within the hox U.

This is a great advantage .in the saving oi`I inie. in pointing out a inarked advantage ol'l our vVrinding devices, vie vfonld state that the stri upon the druin is always borne hy univ al joint 17 to a short shaft V4 hearing vso L ins' (.ruins V and Y lOne o'l' these t i l o l l Winding drains V is `provided Twith a rope 18, 19, and the other Winding druni V2 provided ivith a reversely Wound rope 20, 21. @ne on d ot the rope 20 connects with the forvfard arin 24 rigidly connected to trie upright shalt ol' the caster vheel J and the end 1S o'l' the rope ol the other drinn V connects with the reaiavardly extending arni 22 oi the shalt ol' the caster ii/'heel J. ln like inanner on the other side ol' the machine the end 1Q ol' the rope ol' drurn V/ connects 'with the rearvfardly extending arni 3 and the end 21 of the rope oi the drinn V2 connects vwith the lorvfardly extending arni 25 ol' trie upright shaft oi the caster Wheel J. By this ar rangerrient it Will he seen that the turning oll the drinn Y and V2 in a given direction Will impart to the rope 1S, 1', a reverse inovement l'roni the direction ol' the rope 2l), 21, which causes a dellection oi' the arins 22, 24, and 25, in parallel relation to each other so as to change the plane ol the caster Waeels J and J in relation to the line ol advance, which gives the desired steeril g el'lzect. 1nstead ol the arrangement described, chains Working on sprockets or jointed rods Working on gears Will acconipl'sh the saine result and are Within the scope of our invention.

Th .trarne oll our lnachine consists or" the inclined braces L and L2 on one side and l] and L3 on the other, which are ljointed together in pairs at the top and lrept l'roin spreading by the cross har M which acts as the tulcruni of the hoisting trarne hereinbefore described. N and N, see Fig. 3, are diagonal cross braces to stilien the side iraines. The hoisting traine consists ol the rearwardly converging braces l) and P, the bottoni arins G and O and the upper arnis R and it with braces Y and Y extending 'l'roin l and if. up to the l'nlcruin har M, as seen in Fig. 3. The box traine hinges on the cross har as a `lilcruin and the cross har R2 d end o'l' the hoisting :traino at the for-.va joining the two sides ol' the saine also acts a iulcruin on v. `iicl is supported and tilts the grain hox U or che hay iorl when that used in the place oi" the grain 120x.

rllhe grain hox U, see l, tapered at its roar end to coni'orin to the shape of the niaehine and rests 1when being i'illed on the axle A, heilig held in position hy the rods Z, Z and 10, 10, the rods Z, Z, being pivotally connected to the upper edge ot' the grain box. For gathering hay, the t'ork shown in Fig. G is pivotally connected on the cross bar l? in the saine relation occupied by the grain box U, as seen in Fig. 2.

The nieans 'l'or holding' the box or fork parallel to the ground while the load is being raised, owes its efficiency to the 'tact that said box or l'ork hinges on the Yl'ront ot the lii'iistingg 'traine and travels in a circle whose center is the 'tuleruin bar M, while the box or 'l'orli itsellI is maintained in horiziintal position by rods Z, Z, which ti'avel in a circle whose eenter is the cross bar M connecting' the traine nieinbers S, S, at the top. ly having;l the ineinbers S and S longer than the vertical depth ol' the box U tiie rods Z, 7i, allow the box or l'oi'li to gradually dip downward in vl'ront as the load is being' raised and thus niaintains the horizontal position ol said box or tork.

ille will now describe the incans ttor dunu ing the @rain box U, re'l'ei'enee being had to llhe iront end ol' the grain box consists ot' a hinged door il, hung' to the box at its lower end 1G and provided at the top with catches 1l., il, which hold it closed. llroni this end door at a point below the catches a i'o .we w extends over pulley 12 and under pu ley i3, thence over a pulley on 'the cross bar it/ down to the rear lower end ot' the traine 8, it), S, said rope 'w being attached to said rear end ot `the t'ranie within easy reach ot' the operator. rihe rear end otA said traine is provided with a perforated tail piece trg, through which extends the upper end ol' a slidinfY bar T. m is provided at its This bai' i lower end with a slidingI keeper t" which einbraces a parallel bar T2 Vfixed iii vertical position upon the rear end olI the l'raineworl; immediately adjacent to the position ol' the operator. ilhe bar T2 is provided at its ugper end with a lleeper t2 which einbraces the parallel bar T. The upper end ol' the bar T is provided with a suitable head 7i. above the tail piece fici, which head holds the traineworl; S, 10, S, immovable and prevents the tilting ol' the box U on its reciting; cent er it. Around the bai l is wound a spiral spring' i. iii-"hen the bar is in its lowest position its head 7i holds the traine S, iii, down by the ,locking engagement o'll a l'oot lever 5 which engages with the 1xeeper t at the lower endet' the bar T. ili'hen, however, the toot lever 5 is turned troni engagement with the lowei' end oli the bar T then the bar T is l'ree to rise :troni the weight ol' the loaded box, the leeper t sliding up over the bar t2 and engaging with a cushion enect the spring' t. rthis upward inovenient oi' the bar il allows Vthe traine S, 10, S, to nieve upward and forward causing' a thrustnpon the bar Z, which turns the grani box U upon its 'ulcruni center tlg.

To dunip the load the catches .il

holding' vthe i'i'ont end ot the box 'it in position, are

raised and the rope fili is slaclfened, which al lows the l'i'ont end ol' the box u to tui'n upon its hinges lo and drop downward hanging in a if'ertically pendent position as shown in dotted lines in Fig'. 2. Ylt will be noticed that. in the position shown in Fig. 2, the box is tilted upward so that its l'ront edges are not in a true vertical position, but the upper part ol' the end ot the box is slightly canted backwai'd. By reason ol' this Ytact when the hinged end ii, oll the box drops down, it is not in alineinent with the iront edges ol' the box but. l'oi'ins an obtuse angle therewith. By reason olI this angle and the tact that the pulley i2 is soine distance in rear ol' the l'ront ol' the box, the pull ol' the rope w is in rear o l` the hinged center 16 and hence the operator is enabled by hauling' bacli upon the rope iii to draw the pendent box dooi' 'a l'roin its dotted line position up to a position closely :uun'oxiniatine' the bottoni ot the box wliei'e it is out ol` the way ot the stack ol' grain over which it is placed. Now to coinplete the duinping process the l'oot lever 5 at the i'eai' is liclced l'orward i'hus releasing' the rod T and allowing; it to slide upward on i'od '.l`l until stopped by the spring held at the upper end oll rod T2. This allows the traine 8, 10, S, to niove l'oi'ward and consequently the box U dips downward and l'or Yard at its lower end upon its ll'iilcruin itz, thus discharging' its load on to the stack. The rope liii holding' the l'ront door ot the box against its bottoni is now loosened and the box is now canted downwardly as shown in Fiel'. 2, the l'orward edges ol said box when in this position are arranged at a reverse angle in relation to the vertically pendent door 'it with the result that the rope is now on the opposite side oll the hinged center 1G, so that the pulling' upon the rope fw will close the hinged door iiiy up against the edges ol' the box l'or reengagen'ient wi th the catches 1 l. vlit will thus be seen that the operation ol' adjusting' the door u to its open position and the closing it again are ell'eeted by the opei'ator l'roni the rear end ot' the inaehine by siniply operating' through the rope fio.

To operate the niachine, see Figi'. l., the horses are hitched to the double tree K and the machine nioved forward beside the header until a sull'icient load oll headed grain has been received l'roin the header elevator into the box ll. rthe niachine is then driven to the stack and when at a proper distance therel'roin, depending; upon the height ol' the stack, the clutch C is thrown into engageinent with the gear E by ineans ot' the lever 14 at the i'eai' operating' through the pull rod "di and elbow eranlk $13. liilhen the di'iiin has wound the load to the dfsired height, the I clutch C `s d iseneae'ed by ineans ot' the lever 14 and the machine advanced to the desired place on'thc stach on which the load is to be i diiinped. The catches ll having been prel. fi. 0

viously disengaged, the rope w holding the front door of the box in place is loosened allowing the door to swing out and down, said door being pulled up and against the bottom of the box as hereinbefore described. As the headed grain is packed tightly against the front door its pressure will immediately cause the door to swing out. rhe operator then disengages the foot lever 5 and allows the load to dump. This may be done gradually if desired, by the operators holding on to the tail ieee we of the frame member 8 acting as a ever, thus causing the box to tip slowly. `When the load is dumped the front door u of the box is pulled baels by means of the rope in and the box U is tilted bach into position by means of the lever frame 8, lo, S, and the lower end of the vertical bar T is reengaged by the foot lever 5. Clutch C is then engaged With gear D, pawl 2 is released by means of the foot lever 4 and the machine started forward and Wheeled sharply away from the stach by means of the steering gear and the box is lowered while returning to the header.

lt vvill be seen from the foregoing that every operation except the raising of the catches 11 can be performed from the position of the operator on the rear end of the machine. The catches 11 are raised by the loader before he leaves the box prior to its being elevated.

For stacking hay or grain in the straw the fork shown in Fig. 6 is employed in the place of the grain box U of Fig. 2 and its operation with the single exception of the manipulation of the door u is the saine as that hereinbefore described.

ln defining our invention with greater clearness We Will state that We are aware that the hoisting frame of a hay stacker has been heretofore operated through a rope extending to the Winding drum, in which the drum was operated through the agency of one of the running Wheels only. ln the heavy strain of lifting a large load of grain, the engagement of a single Wheel with the ground is insufficient to supply the needed power, so that said single Wheel is liable to slip espeeially on soft ground or When in a cavity in the field. in our invention it will be seen by reference to Fig. 4 that lthe drum B is driven by the axle A positively from both Wheels, the clutch C transmitting the power of both Wheels alike alternately to the two bevel gears E and l), iThis engagement of both Wheels of the stacler with the ground utiliZes their conjoint tractive strain for the operation of the drum B and the raising of the load.
